HYBRID POWERTRAIN SPEED CONTROL |
| 摘要 |
In at least one embodiment, a vehicle powertrain includes an engine and an electric machine mechanically coupled by a clutch. The powertrain also includes a torque converter configured to fluidly couple the electric machine to an output shaft. A controller is programmed to command a rotational speed output of the electric machine to the torque converter based on a predicted torque delivered across the clutch. The controller is further programmed to modify the command based on a difference between the commanded rotational speed output and an actual rotational speed output of the electric machine. |

1. A vehicle powertrain comprising:
an engine and an electric machine mechanically coupled by a clutch; a torque converter configured to fluidly couple the electric machine to an output shaft; and a controller programmed to command a rotational speed output of the electric machine to the torque converter based on a predicted torque delivered across the clutch, and to modify the command based on a difference between the commanded rotational speed output and an actual rotational speed output of the electric machine. |
